React Native and expo for web

It depends.

On large-scale apps, I think having something like:

• “if ios, store in secure storage, if android, store in secure storage, if WEB, store in local storage of if X then store in database on web app”

Is not ideal.

So for small scale apps, where data is primarily stored on a server / not on device, I’d highly recommend using expo for both, it’s incredibly easy. But if you have a lot of local data, that data will need to be sqlite/ secure storage on mobile, and a remote database on web, leading to messy / complex code.

If it’s for internal use, most likely the storage will be on a database, so I would recommend using expo for both.
